text: Here's my go to in Python3: bytes.fromhex('020a0d')
  From there you can interpret how you'd like.
  Python 3.7.6 (default, Dec 30 2019, 19:38:26) 
  &gt;&gt;&gt; hex_str = '020a0d'
  &gt;&gt;&gt; bytes.fromhex(hex_str)
  b'\x02\n\r'
  &gt;&gt;&gt; 
  
  As an aside, I've found that storing things as ASCII Hex is one of the better RE habits I've gotten into. You can share the data with others, mark it up, examine it in any editor or IDE. Much better than pushing around an actual binary file.
